Why does iPhone touch have to be skin to skin?

With the human body as a conductor, it needs to use force to press, and at the same time, it needs temperature to make the touch capacitive screen of the iPhone react to local conduction

When other items touch the screen of the iPhone, the iPhone will not react and need to be touched, so as to avoid too many wrong operations.

iPhone is a thermal touch screen in fact, it doesn't have to be contacted.

The sensors used on the iPhone are much more complex, and of course they can also include what kind of pressure, light, and of course.

Only contact can simulate these conditions, and it is not just by temperature.

When talking on an iPhone, when the phone is attached to the distance sensor at the top of the screen, the screen will automatically turn off the backlight;

And if your screen is close to your face, you can't turn it off. It could be that the proximity sensor is broken or the system software is malfunctioning.

You can suspect the problem of the system software first, and try to completely restore the phone to the factory reset state. No, I can only find Apple after-sales to solve it.

The proximity sensor is broken. It's the little transparent dot on the top of the screen.

There are many reasons why this may occur. First: the posture or position is slightly wrong and is not felt by the sensor.

Second: there is a temporary malfunction of the system (I have seen it, a big reboot is fine.) Third:

The hardware was destroyed when the shell was replaced. The principle of the iPhone lifting the head screen lock when talking is that there is a light sensor slightly above the handset of the mobile phone, which can be seen when you look closely under the sun. When there is an opaque object covering the area during a call, the sensor will know about it and lock the screen.

You try to hold the phone in your hand during the call, and cover the earpiece and the large area slightly above with the palm of your hand to ensure that the light is not transparent and then see if the screen is not extinguished. If you still don't lock the screen, then it's a matter of changing the shell. Ask you, what do you mean by changing the shell of the iPhone, or changing the protective shell.

The good thing is that there is no ...

And you can't put it with your iPhone, otherwise you'll scratch the machine, and it's useless.

You can't draw with a stylus that's so thick It's a complete scam.

The touch screen is faulty and needs to be replaced, which costs about 200 or so.

It's not very clear how many points you can touch at most... But when I play puzzles on Apple's iPad, I can move ten different puzzle pieces at the same time with ten fingers. That is to say, from the iPad alone, it supports at least 10 points of touch (more is not clear.)

Not so many fingers ha)。。 The iPhone should theoretically be the same.

Both iPhone and iPad iTouch support up to 10. I feel that the iPhone series of multi-point touch screen technology is the best, the error rate is less, and it is not pressure sensitivity and resistance induction, so it is also convenient to use, but you must use something fleshy to touch it, overall, the iPhone is the best, but it is a little expensive, at least the touch screen is not regretted.

Support up to 5 touches, 1st floor and 2nd floor. Do you think that putting two hands up is a 10-point touch? Don't be so exaggerated.

Bottom right corner I ......In the upper right corner, set ......The interface settings are ......Just 3 colors**......It's all ugly ......

About yourself to modify the background**, warm reminder,chat bg@2x this file corresponds to the chat background picture。 The user bg@2x corresponds to group background images and spatial background images. File sizes are available to choose from and love crazy 4 wallpapers in a size of 640 960.

Here is the addition of the graffiti background** Modification method in the C2B of the Blue Doodle. background@2x corresponds to the graffiti background. The size is 640 839

Of course, this size is not a hard indicator.

It should be noted that ** must be in png format. Remember to put a suffix when naming. png removed. Otherwise, it won't work.

If someone likes transparent chat message bubbles, they only need to delete the two bubble files nor@2x in the blue folder, Chat Recive nor@2x and Chat Send, and replace these two files if they need to change the color.

The file in the upper column of the theme is the header bg@2x and the file in the lower column is the chat bottom bg@2x. If you like to toss, you can change the background of the upper and lower columns.

The replacement path is var mobile

I wanted to change it too, but all I saw was blue, black, red. It seems that there is nothing else that can be changed!

I also have this kind of problem.,I jailbroke before.,It's a plug-in conflict.,It's good to delete the plug-in.,Now I haven't jailbroken for a year.,This kind of problem occurs again.,I'm also having a headache.。

If there is a problem with the touch screen, change the screen, or go to the manufacturer for repair.

Look at the serial number,Your packaging should have a line of small black letters on the outer packaging cardboard shell,It seems to be a number + English,You can enter this number into Apple's official website for detailed verification,From the production date to。。。 All kinds of details... And even simpler, as long as you can connect iTunes, it means that your machine is genuine, no doubt!
